SPECIFICATION forming part of'Letters Patent No'. 301,703x dated July 8, 1884.

(No model.)

To ali whom t may concern:

Be it known that I, GEORGE l?. FENNER., a

London, in the county of New London and State of Connecticut, have invented new and useful Improvements in Printing-Machines, of which the,A following is a specification.

This invention relates to stop-cylinder printing-presses for lithographie and other purposes; and it consists in' certain novelmeans sion-cylinder, whereby, among other things, v

the intervals of motion of the cylinder'inay be varied relatively to the motion of the traveling bed, without altering the press.

This invention is illustrated in the accompanying drawings, in which Figure lis a side elevation with parts of the frame broken away. Fig. 2 is a horizontal section on the li ne x x, Fig. il. Fig. 3-is an end View, partly in section, looking from the left-hand side of Fig. l, and omitting one side of the machine. Fig. 4 is a detail cross-section on the line y y, Fig. 2.

` Similar letters indicate corresponding parts.

The letter A designates the press-frame, having sui-table hearings for the impression-cylinder B and suitable guideways (not shown) for the traveling hed B. At one end of this frame is arranged the driving-shaft C, from which motion is transmitted` by gear-wheels C C2 to the ina-in shaft D, and from this shaft motion is in' turn transmitted by the usual crank, D', and connecting-rod D2 to the rack-wheel D3, which gears into two racks, Dt Da-one xed to the base of the machine, and the other to the traveling bed, for'i'mparting a reciprocating motion to the latter, in the usual manner. The impression-cylinderBreceives its motion from the traveling; bed B through a second rack, B2, fined to the bed to gear into a cog-wheel, B3, of the cylinder, also in the usual manner, a portion of the cogs of this wheel being cut away, as shown in Fig. 1, leaving a space through which the bed may travel under the wheel without turning it when the cylinder is at rest. At a point opposite to the space left in the wheel B3, as last stated, the impressioncylinder B carries a catch, F, which is radial thereto, and adapted to engage with one end of a catch-lever, F', having its fulcrnm at the other end in astnd, F2, of the press-frame, and

having a longitudinal slot, F, in which is fitted a block, F", constituting a key, as hereinafter explained. From this key F4 projects laterally, and in this example on two opposite sides, a locking-pin, F5, which is adapted to alternately enter either of two recesses, G G- one formed in a rod, G2, and the other in the press-frame, at such points that under certain conditions these recesses are brought opposite to each other, as shown in Fig. l. The rod Gl is a medium for operating the catch-lever F', and straddles this lever at one end, where it is bifurcated, as shown in Fig. 2, while at the other end the rod carries two roller-studs, G3, through both of which it engagesa cam, Gt, of the main shaft D, so that thel rod receives a reciprocating motion from such shaft. Said catch-lever-operating rod G2 rests in guides G5 of the press-frame, and in a proper part of the rod is formed a longitudinal slot, G6, (see Fig.` 1,) for allowing it to clear the main shaft.

To the key F* of the catch-lever is connected, as by means of a link, F, one arm of an adjusting-lever, H, in the other arnrof which is a not-ch, H, corresponding to a notch, H2, in one arm of an impelling-lever, H3, the other arm of which carries a roller-stud, H",

entering a grooved cam, H5, of the main shaft D, whence the impelling-lever last mentioned 8o receives an oscillating motion, the other or adjusting-lever, H, remaining stationary under normal conditions. Both levers H H are fulcrurned on a shaft, HS, and those arms thereof containing the notches H H2 are equal in S5 length to each other, so that the notches which are at the extremities of the arms may register with each other in a certain position of the levers. When the adj listing-lever H is at rest, the key F* of the catch-lever Ff adjusts itself to bring the locking-pin F5 into the recess G lof the catch-lever-operating rod G, as shown in Fig. 1, and by this means the catch-lever is united to the operating-rod to share its motion, in which motion such lever takes the proper positions for engaging the catch F to stop' the cylinder, or for disengaging thecatch to start the cylinder, in the usual manner. Then in the motion of the impelling-lever H3 the notch thereof registers with the notch of the adjusting-lever H, these leversare interlocked by means of a latch` I, which enters the notches at the proper moment, and in the ensuing motion of the adj Listing-lever, derived IOO from the impelling-lever, the key F* of the catch-lever is lifted to bring the locking-pin F5 out of the -recess G of the catch-lever-operating rod, and into the recess G of the pressframe, whereby the catch-lever is not only disconnected from the operating-rod, but also locked in position, so that the operating-rod may continue its motion without acting on the lever. In order to adapt the lever-interlocking latch I to the motion of the adjusting-le- Ver H jointly with the imp'elling-lever H3, it is pivoted to the adjusting-lever, as at I', and for the purpose of engaging the lever-notches the latch is provided with a toe, I2, (best seen in Fig. 5,) at one end. Said motion of the adv j Listing-lever His regulated by means of the cam H5 of the impelling-lever to take place when the impression-cylinder has reached the stopping-point, andinasmuch as the catchlever F' is locked at that period it performs the function of stopping the cylinder. Said motion of the adjusting-lever H is also regulated by the same means to keep the catch-1ever- F' in a locked position, and thereby hold the impression-cylinder stationary until theadjusting-lever is disconnected from the impelling-lever by the Withdrawal of the interlocking latch I from the lever-notches, which takes place at fixed intervals, as next explained. rIhe latch I engages with one end of a locking-lever, J, which has its fulcrum at the other end in a shaft, J', and is capable of moving laterally 011 this shaft to alternately engage either of two stop-cams, J 2 J3, whence it receives a vibratingy motion of the vproper nature to set the latch and keep the adjusting and impelling levers H H3 interlocked by its means during the required period.

The cams J 2 J 3 are arrangedin juxtaposition on a shaft, J and thelocking-lever J engages the same by means of roller-studs J5, applied to opposite sides of the lever to ride on the cams. Said cams Jz Ji moreover areleft loose on their shaft, and are geared with the main shaft D, as by cog-Wheels K K', to receive a revolving motion of 4different speed, respectively, the speed of one being a multiple of the speed of the other, and the whole being so regulated with relation to the shape of. the cams that when the locking-lever is in engagement withfone cam the impression-cylind er Bis held stationary, as before explained, during one interval of motion of the traveling bed B', while when such lever is in engagement with the other cam the cylinder is held stationary during two such intervals, and inasmuch as it is only necessary to change the position of the locking-lever to vary'these conditions, no alteration of the press is required.

For the purpose of adjusting the lockinglever J relatively to the stop-cams on its shaft, ahand-lever, JB, and connecting-rod J 9, or any other suitable device, may be used.

The means thus far described for setting the latch I operate automatically; but in order to permit the impression-cylinder to be stopped for an indefinite period, provision is made for setting the latch also by hand, as follows: 'Io a proper part of the press-frame is fulcrumed a hand-lever, L, one arm of which engages the latch I at the end opposite to the locking-lever J through a spur, L', of the latch in such a manner that by a simple movement of the hand-lever the latch may be set to the required position to be held therein by fastening the lever or otherwise. In the example shown both the locking-lever J and the hand-lever L are left disconnected from the latch I, and a spring, L2, is used to return the latch to an unlocked position; but such levers can also be connected to the latch. l

The sheet-flier is here shown, and consists of the shaft N and arm N', the shaft being attached tor rock-shafts N2, one of which has a toothed segment, N3, engaging alike segment, Nt, on a lever, N5, having a roller-stud, N7, engaging a cam, NS, on main shaft D. Granks O O', having screws and notches, detachably connect the shaft N to the rock-shafts.-

I have illustrated in connection with the press a sheet -flier, N N', and mechanism whereby the forward movement of the flier toward the cylinder is effected from the main shaft D; but such sheet-flier and operating mechanism are not herein claimed. Ihave also illustrated damping-rollers Q and means for supplying them with water; but neither do I herein claim such featuresi as all will constitute the subject-matters of separate applications for Letters Patent.

Vhat I claim as new, and desire to secure by Letters Patent, is- 4 y 1.\ The combination, with the impressioncylinder and its catch, of the catch-lever, the catch-'lever-operating rod, the key ofthe catchlever having a locking-pin adapted to alternately enter recesses, one in the operating-rod and the other in the press-frame, and ameans, substantially such as herein described, for automatically adjusting the key to such recesses.
